Data creation device, data creation method, and program

Abstract

The present technology relates to a data creation device, a data creation method, and a program by which a face image dataset suitable for AI model learning can be obtained. The data creation device creates, by partially or wholly changing a creation parameter which is obtained by conversion of a source image of a freely-selected face to a numerical value, a larger number of input creation parameters than a predetermined number from the predetermined number of the creation parameters of the source images, and creates, by creating a face image data item on the basis of a plurality of the input creation parameters, a face image dataset including a plurality of the face image data items. The present technology is applicable to a data creation device.

         10 . The data creation method according to  claim 9 , wherein,
 by performing cleansing on the face image dataset, the data creation device creates the final face image dataset that satisfies a predetermined requirement.   
     
     
         11 . The data creation method according to  claim 10 , wherein
 the predetermined requirement is the number of the face image data items constituting the face image dataset, a resolution of the face image data items, an attribute to be subjected to labeling, or statistics of attribute values of attributes of the face image data items.   
     
     
         12 . The data creation method according to  claim 1 , wherein,
 by converting the source image to a numerical value, the data creation device creates the creation parameter according to the source image.   
     
     
         13 . The data creation method according to  claim 1 , wherein
 the data creation device creates the face image data items by using a GAN or a VAE according to the input creation parameters.   
     
     
         14 . A data creation device comprising:
 a parameter creation section that, by partially or wholly changing a creation parameter which is obtained by conversion of a source image of a freely-selected face to a numerical value, creates a larger number of input creation parameters than a predetermined number from the predetermined number of the creation parameters of the source images; and   a dataset creation section that, by creating a face image data item on a basis of a plurality of the input creation parameters, creates a face image dataset including a plurality of the face image data items.   
     
     
         15 . A program for causing a computer to implement a process comprising steps of:
